Purpose: This study was assessed to investigate the change of subjective and/or objective symptoms and the light transmittance of lens caused by the use longer than recommended wearing time of daily disposable circle contact lenses (circle lens) in dry eyes. Methods: Three daily disposable circle lenses made of etafilcon A, hilafilcon B, and nelfilcon A were applied on 30 dry eyes with smaller tear volume than normal eyes in their twenties free from any eye diseases by when subjects complained any kind of discomfort. On the first and the last days of lens wearing, subjective discomfort, blinking rate, lens centration on corneal surface and visible light transmittance of lens were recorded at every case and compared. Results: The circle lens wearers complained subjective discomfort and quit the lens wearing when they wore the circle lens longer than 10 hours even though there were some difference according to the lens materials of daily disposable circle lens. However, around 20% of dry eyes could wear the circle lens made of non-ionic materials longer than 40 hours. Dry eyes showed most sensitive feeling of subjective discomfort against the circle lens made of etafilcon A among three different lens materials. On the last day of lens wearing, the representative subjective discomforts were irritation, stiffness, dryness and tiredness. When the subjects wore circle lens more than the recommended time, blinking rate was significantly increased about 20~30% regardless of lens materials when it compared with the values right after lens wearing. On the last day of lens wearing, the vertical direction of lens centration was shifted to pupil center however, its distribution in horizontal direction was wide compared with the distribution right after lens wearing. Especially, the centration of etafilcon A lens was unstable. Furthermore, the visible light transmittance of 3 different circle lenses in dry eyes has significantly been reduced around 15% averaged. Conclusions: From these results, it was known that the increase of dryness and stiffness caused by overusage of daily disposable circle lens induced excess irritation and decreased visible light transmittance and caused significant more blinking, which provoked lens decentration. It was also revealed that dry eyes showed sensitive reaction subjectively and objectively against the overusage of circle lens made of high water content/ionic lens material even there were some difference of the degree depending on the individual and the lens material. Thus, this research can be suggested as the basic reference for the education about some unexpected problems and the side effect caused by the wearing of circle lens in dry eyes.

외상성 전방탈구의 경우 일차성 탈구이거나 일상생활에 큰 불편을 호소하지 않는 불안정성이 있을 경우 및 비외상성 다방향 불안정성의 경우 보존적 치료가 바람직하며, 10대 및 20대의 재탈구로 인한 불안정성이 유발될 경우 관절경적 혹은 개방성 Bankart 술식을 통하여 관절순의 해부학적 정복 및 술 후 잘 조절된 재활치료를 시행할 경우, 좋은 결과를 얻을 수 있다. 치료 방법의 선택 시 가장 중요한 요소는 환자의 원하는 결과를 만족 시켜줄 수 있는 치료 방법을 선택하는 것이며, 이는 불안정성의 원인, 정도, 탈구의 횟수, 환자의 활동도 및 재활 의지등을 종합적으로 감안하여 결정되어야 한다.

컴퓨터기술은 어디로 가고 있는가? 이 물음에 대한 답은 바로 입는 컴퓨터일 것이다. 입는 컴퓨터는 완전한 기능을 갖춘 컴퓨터를 몸에 지니고 다니면서 언제 어디서나 원하는 일을 할 수 있게 해준다. 처음 만들어진 컴퓨터는 큰 건물만 했으나 책상 위에 올려놓을 정도에서 들고 다닐 수 있는 크기까지 작아졌다. 그러나 노트북 컴퓨터는 아직 휴대하기에는 불편함이 많다. 이 문제를 해결한 제품이 PDA(Personal Data Assistant)이다. (중략)

서울대학교병원의 ESCO사업이 한창이다. 올해 말까지로 예정된 이 공사는 110V 전압을 220V로 전환하는 승압공사와 고효율 조명기기 교체사업이 동시에 이루어진다. 연간 약 1억6천만원 정도의 전력비 절감효과가 있을 것으로 기대되는 이번 사업은 병원을 이용하는 환자들의 불편을 최소화하기 위해 야간작업만 실시하기로 했다. 작업능률은 다소 떨어지더라도 환자를 먼저 생각하는 마음이 엿보인다.

강력한 항레트로바이러스 치로(highly active antiretroviral therapy, HAART)의 도입으로 HIV 감영인의 기대여명(life expectancy)이 비감염인과 큰 차이가 나지 않을 정도로 향상된 것은 널리 알려진 사실이다. 하지만 평생 동안 약물을 복용해야 하며, 이에 따른 약물 부작용, 약제 내성, 경제적 손실, 불편함 등이 문제가 되고 있으며, 이를 극복하기 위한 다양한 치료법에 대한 연구가 진행 중이다. 이 글에서는 최근 발표되거나 진행 중인 새로운 치료 방법에 대해 간단히 알아보고자 한다.

미국의 사례에서 보면 전체 입원환자 중 약 7.2% 이상이 당뇨병환자이고, 이것은 비당뇨인에 비해 2.4배의 입원율에 해당한다고 한다. 우리나라에서도 사정은 비슷해 보통 1000병상에 당뇨병환자가 130명꼴에 달할 정도로 적지 않은 수를 보이고 있다. 그도 그럴 것이 당뇨병환자라면 아무 증상이 없고 불편이 없어도 혈당이 높다고 입원을 권하곤 하는데, 그 내막을 알아보자.

The purpose of this study was to provide the accurate information on improvement of visual life by examining old age's eye refraction state and investigating distribution of ametropia in old age. The test was performed the visual acuity test by object and subject methods to over 60 years of age. The results were as follows: 1. As the result to investigate the inconvenience degree of visual life, the subjects appealed 81% for very inconvenience and 14% for a little inconvenience. 5% of them didn't feel any inconvenience in visual life. 2. The eye types were 1.7% for emmetropia, 10% for myopia, 74.7% for hyperopia, and 13.6% mixed astigmatism, respectively. 3. The axis of astigmatisms were 65% positive for indirect astigmatism, 8% for direct astigmatism, and 27% for oblique astigmatism, respectively.

The purpose of this study is to examine hospital noise level and discomfort due to noise. The subjects were 156 patients from University hospital in Taegu. The data was collected from April 10 to May 14, 1997. The collected data were analyzed by SPSS program using percentage, paired t-test, ANOVA, and Pearson Correlation Coefficient. The results were as follows ; The mean score of noise level was 1.62. There was no statistically significant difference in noise level between day and night. Patients perceived higher noise in the categories of conversation of visitors, conversation of care providers, noise of air conditioners, and the conversation of nearby patients than others during the day. Patients perceived higher noise in the categories of noise of air conditioners, conversation of visitors, conversation of care providers, and telephone ringing than others during the night. There were no statistically significant differences in noise level among the 4 wards during the day or night. Discomfort was due to the forementioned noise, categories of high scores were sleep disturbed, irritated, not so bad or not noisy, and noisy. To avoid noise, the subjects coped by putting on a quilt, going out, sleeping, opening or closing the window or door, and plugging ears. These results indicated that hospital noise have a negative influence on patients' health. So noise levels should be reduced in hospitals.
